FYI guys: Maximum PC magazine has just introduced it's "Dream Machine 2013", a US$16,585 beast, in it's (current) September issue, with a
RIVE and 3970X. They report "as of this writing, the Dream Machine would be ranked
#6 on the 3Dmark Hall of Fame leaderboard," using 4 water-cooled titans! They also reported they were only limited on OC to the limit of their 1600W PSU - they did not however specify whether they were limited on either the GPU cards OC or the CPU OC.
"we were able to easily push our" 3970X "to 5GHz all day. Six cores buzzing along at 5GHz with Hyper-threading gives us a great balance of core count and frequency. Enough that the Dream Machine has the gusto to compete with newer quad-core chips in workloads that can't exploit all 12 threads."
There was also a slightly surprising optimistic comment: "The best part of going with LGA2011 is that we'll get a CPU upgrade in a few months when Intel finally releases Ivy Bridge-E." Take that sentence with a grain of salt though, as I've read elsewhere that the IB-E may require a new chipset.
So you see, as I have been preaching to ppl months ago, SB-E is still "King of the Hill," even after the release of Ivy Bridge (not -E). And the RIVE is the best SB-E board made (I love my RIVE).
